AZ150 Galvalume Steel Coils

Brief Introduction

Our AZ150 Galvalume Steel Coils, also widely known as Aluzinc Steel Coil, strictly comply with ASTM A792 galvalume coil global industrial standard, fully tailored for medium and high-end overseas buyers with three core competitive edges: standard alloy coating formula, premium comprehensive performance, and full customized service.

1. Standard International Coating Formula

All coils adopt the authoritative 55%Al-43.4%Zn-1.6%Si hot-dip alloy coating formula specified by ASTM A792. Silicon stabilizes coating adhesion to avoid peeling during deep processing; aluminum forms a dense anti-rust barrier layer, while zinc provides sacrificial cathodic protection. The AZ150 coating weight (150g/m² double-sided) delivers thicker, uniform coverage without missing plating, far exceeding low-grade unstandardized coated steel in stability and durability.

2. Core Premium advantages for Mid-to-High End Markets

As a top-tier coated steel material, this ASTM A792 galvalume coil owns standout advantages matching high-standard engineering demands:

3–6 times stronger corrosion resistance than ordinary galvanized coils, resisting coastal salt fog, industrial acid rain and outdoor UV erosion for over 25 years;
Stable heat resistance up to 315℃ without discoloration or coating failure, ideal for solar brackets, commercial curtain walls and premium home appliances;
Smooth star-spangle silver surface with optional anti-fingerprint passivation, uniform flatness and perfect paint adhesion for post-decoration.

These superior properties help mid-to-high end clients cut long-term maintenance and replacement costs, forming obvious differentiation from cheap coated steel.

3. Full Customization (Rigid Demand of Mid-to-High End Clients)

We support one-stop customized production for global medium and high-end purchasers of Galvalume Steel Coils:

Custom substrate grade: DX51D, DX52D, DX53D soft forming steel & G550 high-strength steel;
Custom dimensions: thickness 0.17–0.8mm, width 700–1250mm, fixed-width cutting & precise slitting;
Custom surface treatment: passivation, oiled, anti-fingerprint film covering;
Custom packaging & inspection: export seaworthy packing, full SGS/BV test reports per ASTM A792 standard.

We maintain tight tolerance on coating weight, flatness and mechanical properties, rejecting defective products to fully meet strict quality standards of high-end construction, photovoltaic and household appliance manufacturers worldwide.
